TRUCK ATTACHMENT 7 Nathaniel C. Perry, Batesville, Miss. Application April 4, 1957, set-n1 No. 650,746 3 Claims. 01. me -302 'This invention relates to a truck attachment or a wagon attachment and more particularly to an attachment to facilitate the hoisting and emptying of cotton sacks when cotton is being picked in the field or at any other time.

An object of. the invention is to provide an attachment for a wagon or truck which enables the ordinary cotton sacks to be lifted and emptied with a minimum of diiliculty,;the attachment being capable of being applied to a truck, trailer, wagon or any other conveyance;

A further object of the invention is to provide an at tachment for a vehicle of any type, the attachment including such an organization as to be capable of being 31)". plied in many ways to suit the type of vehicle with which it is being used. One such manner of attachment will use a pair of upwardly opening tubes that function as a track within which a vertically operable carriage is movable, there being a latch to hold the carriage in the selected vertically adjusted position to suit the desires of the user. Pulleys are suspended from the carriage and are adapted to receive a rope, on the end of which there is a stout clamp to attach a cotton sack. By use of the attachment, the cotton sack is secured to the stout clamp and is lifted by merely pulling on the rope until the sack is above the bed of the truck or body of the wagon or other vehicle that is used to support the attachment. Then the sack is easily emptied and returned for subsequent filling.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter de scribed and claimed, reference being bad to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

'Figure l is atop plan view of a vehicle with an attachment constructed in accordance with my invention applied thereto;

Figure 2 is a side view of a typical vehicle as in Figure 1, having my attachment thereon;

Figure 3 is an enlarged, transverse sectional view taken on the line 3-3 of Figure 2;

Figure 4 is an enlarged, fragmentary sectional view taken on the line 4-4 of Figure 2 and showing a latch to hold the carriage in the vertically adjusted position;

Figure 7 is a sectional view on an enlarged scale taken on the line 7-7 of Figure 3.

In the accompanying drawing there is a motor vehicle 10 which, in the illustrated instance, is an ordinary truck having a truck body 12. The motor vehicle 10 is understood to schematically represent any standard and conventional conveyance which would be used with an attachment of my invention.

The attachment 14 is applied to the motor vehicle 10 United States Patent 0 2 for the purpose of aiding in the lifting and emptying of cotton sacks 16. Accordingly, the attachment 14 is made of a track that has twov upwardly opening, tubular guide rails 18 and 20, respectively. The rails are constructed of open ended tubular stock and are held in place on the sides 22 and 24 of vehicle bed by means of pipe straps 26 and 28. Bracings 30 and 32 hold the rails 13 and 2t) erect. Bracings 30 and 32 are constructed identically (Figure 6). The bracing 32 is made of two sleeves 36 and 37 having rods 38 and 39, respectively, that are telescopingly slidable therein. Setscrews 40 and 41 carried by the sleeves 36 and 37 bear against the rods 33 and 39 in order to hold them in the selected, extended position. The outer ends of rods 38 and 39 are flattened in order to accommodate bolts which attach the bracing firmly to the side 24 of the truck body 12. Inasmuch as sleeves 36 and 37 are welded to the rail 26, the rail is immovably and firmly fixed to the truck bed. Further aiding in holding the rails 24 and 18 attached firmly are vertically adjustable angle brackets 44 and 46 on the rails 20 and 18, respectively, which engage over the top edges of the sides 24 and 22 of the truck body and which have holes through which the rails 20 and 18 pass.

Carriage or frame 50 is vertically movable in the track and is of generally inverted U shape. It is made of parallel legs or bars 56 and 58, each having a ratchet or rack 59 and 6% formed on its outer edge. Sleeve 62 is attached at right angles to the upper end of bar 56 and rod 64 is attached at right angles to the upper end of the bar 58. Rod 6d is slidably disposed inthe bore of sleeve 62 and held in a selected, adjusted position by means of a setscrew 66 which passes through a threaded aperture 68 in the upper wall of sleeve 62, thus providing the U-shaped carriage or frame (it) with a telescopically adjustable bight portion.

Pulleys '70 and 72 are mounted for rotation in hangers 74 and "76, the latter being suspended from sleeve 62. Rope 78 is adapted to pass over one or both of these pulleys and it has a stout spring clamp 89 at one end. The opposite end is adapted to be attached to eye 82 which is secured to the rail 18.

A pair of cars 90 and 91 are welded or otherwise secured to the rail 20 and support a spindle 92. Lever 93 is pivoted on spindle 92 and has a dog 94 pivotally mounted thereon and engageable with the teeth of rack 59. The dog 94 functions as means for lifting the carriage 50 by elevating the bar 59 in response to oscillation of the lever 93. Accordingly, lever 93 and the dog 94, together with the rack 59, function as a jack for elevating the carriage. There is one such jack in rail 18 and another in rail 20. Pivotally mounted between the cars and 91 is a holding dog 95 which is engageable with the ratchet or rack 59 for securing the carriage 5G in elevated position in an obvious manner. The dog 95 is provided with a handle 96 to facilitate disengaging said dog from the ratchet or rack 59 when it is desired to lower the carriage 50.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, his not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. An adjustable sack hoisting and emptying attachment for vehicles of the type including box-type bodies of various dimensions having vertical side walls, said attachment comprising a pair of tubular guide rails, means for securing said guide rails verticallyon said side walls, a generallyinverted U-shaped frame mounted 'me'ansmounted on said bight portion, the first "named means including vertically adjustable angle brackets mounted on the guide rails and engageable over the top portions of the side walls.

2. An adjustable sack hoisting and emptying attachment for vehicles of the type including boxtype bodies of various dimensions having vertical side walls, said attachment comprising a pair of tubular guide rails, means for securing said guide rails vertically on said side walls, a generally inverted U-shaped frame mounted for vertical adjustment on said guide rails'and' including legs slidably engaged therein, said frame further including a telescopically adjustable bight portion, means for adjusting said frame on the rails, and sack hoisting means mounted on said bight portion, the first named means including vertically adjustable angle brackets mounted on the guide rails and engageable over theto'p portions of the side walls, the second named means including ratchets on said legs, manually actuated'pawls on the rails operatively engaged with said ratchets, and gravity operated holding dogs on the rails engaged with the ratchets for releasably securing the frame in vertically adjusted position.

3. An adjustable sack hoisting and emptying attachment for vehicles of the type including box-type bodies ofvarious "dimensions having vertical side walls, said for adjusting said frame on the rails, and sack hoisting means mounted on said bight portion, the first named means including vertically adjustable angle brackets mounted on the guide rails and engageable over the top portionsof the side walls, the second named 'means including ratchets on 'saidelegs, manually actuated pawls on the rails opcratively engaged with said ratchets, and gravity operated holding dogs on the rails engaged with the ratchets for releasably securing the frame in vertically adjusted position.
